Description

Hair treatment composition.

The present invention relates to a hair treatment composition, to a procedure of hair treatment and the use of certain materials for condition the hair

The hair treatment compositions with clarified are products that are intended to be clarified from hair during use, usually with water, after they have been applied to the hair by the user. Normally, it is desirable. deposit any beneficial agents in the hair and not suppress all of these agents during the stage of cleared up. This deposition can be achieved, for example, using cationic polymers. The rinse treatment compositions They include shampoos and hair conditioners.

Treatment products to leave applied to hair, such as hair styling products, They are not intended to be rinsed immediately After being used. Products may contain agents beneficial for the hair that are deposited in the hair together with the product agent that is responsible for the properties For the hairstyle.

When a beneficial agent for hair is applied to the hair from a rinse product or to leave applied, it may be useful to cause the beneficial agent for the hair to become active, that is, to exhibit its effect beneficial to a greater extent, not immediately after the application, but only after causing the activation of the agent. For example, it may be desirable to activate the agent beneficial for hair only after the hair has It has been heated. This allows the agent beneficial to the hair is supplied to the hair at a later stage of the rest of the rinse product. Also, the beneficial agent for the hair can be protected from air and / or moisture until it is released.

A treatment composition is described for curl heat activated hair in US 4,861,583. The composition employs a certain poly (ethylene oxide) polymer water soluble, linear or branched or crosslinked, which has a melting point of 50 to 80 ° C. The polymer is exposed to the heat of a curly iron and thus confer curly hair. There is not no description in this document of the supply of any Another benefit to the hair or the use of other materials.

EP 0.412.865 describes gels cosmetics containing spheroids in a solid lipoidal substance  non hydrophilic that melts after being applied to the body.

US 6,156,826 refers to the encapsulation of perfumes in hydrophobic particles for a controlled release Perfumes that are encapsulated in particles have a log P value of 1 to 8 and therefore are substantially insoluble in an aqueous phase. In the examples, which are provided in the document, vegetable waxes are used to encapsulate the perfume and there is no mention of any benefit that is associated with the waxes themselves.

WO 01/73412 discloses optional use of visible particles in conditioning compositions of the hair. The particles are not intended to melt when the hair is heated and they are of a substance that can be break down and disintegrate with very little finger rubbing on use and is usually a polysaccharide, oli-gosaccharide or monosaccharide.

US 5,656,280 discloses compositions of emulsions of water in oil in water that can be used for supply agents to the hair and / or skin.

US 5,665,687 discloses compositions of personal cleaning that include liquid grains that incorporate A cleaning agent.

There is still a need for systems that can provide beneficial agents to the hair for the same after a heat treatment stage, they provide benefits other than the supply of hydrophobic materials, such as perfumes

It is known that certain types of particles solids can be used in treatment compositions of the hair. For example, US 5,051,489 discloses waxes of silanol that can be used in a range of different applications, which include lubricating the hair. WO document 01/39729 discloses wax particles having a size of 1 to 300 nm as revitalizing agents for treatment products of hair. EP-A-0346852 describes oil-in-water emulsions containing 1% to 6% by weight of an oil or wax. The document EP-A-506197 exposes particles of solid lipids having a size of 50 nm to 1000 nm for the hair treatment There is no mention in any of these documents heat treat the hair, after the particles have been deposited in the hair.

The document JP-A-11-228.359 describes a shampoo composition containing wax particles having a size of 1 micrometer (1 µm) or smaller and a point melting 50 to 100 ° C. The particles are said to provide benefits of softness, ease of styling and antistatic when hair. Again, there is no indication in the document of it is necessary to heat the particles in order to achieve the benefits.

The present invention is based on the discovery of a system to provide activated benefits by heat to hair compositions that have benefits Surprising about the prior art compositions. In In particular, the invention is based on compositions that provide surprisingly effective hair conditioning benefits and optionally other benefits, when applied to the hair.

According to the present invention, a hair treatment procedure comprising:

i) apply a composition of hair hair treatment comprising particles that have a first non-aqueous phase and, retained in said first non-aqueous phase, a second hydrophilic phase which is a solution, dispersion, aqueous emulsion or a solid or liquid that has a log P value less than 1, said second phase comprising a beneficial agent for hair selected from block copolymers of poly (ethylene oxide) -poli ( propylene) -poli (ethylene oxide) and polymers of polyvinylpyrrolidone or its copolymers in which said first phase does not accuse it has a melting point of 45 ° C to 100 ° C, and is a wax of silicone that has the general formula:

one

wherein R 1, R 2 and R 3 are independently branched alkyl or alkoxy groups or unbranched from C 3 to C 40, K and L are independently integers from 0 to 100, with the proviso that K and L are at minus 4 and when K and L are not both equal to 0, the polymer can comprise random or block groupings or groups L and K; Y

ii) heat the hair to a temperature by above the melting point of the first non-aqueous phase.

The invention also relates to a procedure for manufacturing a treatment composition of the hair in a procedure as described above, which It comprises the following stages:

i) heating the non-aqueous phase so that sheath;

ii) add the second hydrophilic phase to the phase not watery;

iii) heat the rest of the composition until a temperature equal to or below the starting temperature of solidification of the non-aqueous phase and

iv) then add the resulting mixture of step ii) to the heated composition of iii).

This manufacturing process maximizes the capture of the material to be encapsulated.

A variant of the manufacturing process previous is to replace stage iii) with a warm-up of the rest of the composition at a temperature equal to or greater than the point of fusion of the non-aqueous phase (the wax). Preferably, the Wax temperature rises to a maximum of 20 ° C from its point melting, more preferably, the temperature of the wax rises up to a maximum of 10ºC above its melting point. This manufacturing process means that particles are formed that They have the necessary particle size.

It is preferable that the sequence of addition in This procedure is as cited above.

Although not preferred, in some cases they may other components be included in these formulations.

The solidification temperature is the temperature at which the viscosity of the non-aqueous molten phase begins to increase significantly after cooling to temperature atmosphere and a pressure 1 atmosphere.

The melting point of the non-aqueous phase (the most cases this means wax) is measured by DSC (differential scanning calorimetry). The melting point cited in this description is the peak of the curve obtained via DSC.

A further aspect of the invention is the use of particles comprising a non-aqueous phase having a point melting from 45ºC to 100ºC to condition the hair, heating hair treated with particles at a temperature above melting point of the non-aqueous phase. The benefits Conditioners include easy styling, smoothness, softness, body, volume, flight, abundance and texture.

The invention is based on the discovery of that it is possible to provide a beneficial agent for hair to starting from particles, when the agent is relatively hydrophilic and, surprisingly, that particles can be deposited Effectively from hair treatment products. The particles can provide a property or a combination of two or more properties that are beneficial to the hair after of heat treatment of hair, for example, during combed or dried with heat at an elevated temperature. They are Particularly preferred particles that can provide hair styling benefits and that can be supplied to from a shampoo or conditioning composition with rinse. The invention is also based on the discovery of particles that they are able to be effectively deposited in the hair and, at continuation of a heat treatment of the hair to melt the  particles, can provide conditioning benefits to hair. In certain embodiments, the invention involves the unexpected discovery that the fusion of the particles is capable of supplying hydrophilic materials to the hair, despite the hydrophobic outer environment of the particles.

The fusion of the non-aqueous phase of the particles provides at least part of the conditioning benefits of the composition (as ease of styling), while any beneficial agent for hair that is retained in the particles can provide a benefit, which can be a conditioning benefit or other hair care benefit, after being released from the particles after the fusion of the non-aqueous phase
